Dear all
I get the following error message when I try to load one specific RData object
in R:
Error: ReadItem: unknown type 64, perhaps written by later version of R
The error message is odd because (a) this RData object was created just one hour berfore
in a previous script (in a series of R scripts called in batch mode), so it would seem
to me that it has been created by the same version of R that is now calling it (b) this
script is "looping" over several scenarios and years, and the error only occurs
for one very specific combination of scenarios and years. This object is about 6 Gb
large, which is the same size as the other objects that were called in previous
instances.
What is 'odd' is that you missed the 'perhaps'.
The most likely explanation is an I/O error when the file was written:
it is 'perhaps' corrupted.
I load the RData with the following command (where pathsony[[rdata]] is the
folder with the RData and skimlistrdata is the file I try to load):
load( file.path(pathsony[[rdata]],skimlistrdata))
The problem occurs both when I run the script in batch mode or when I run it
interactively.
I use a "x86_64-pc-linux-gnu" and "R version 3.1.2 (2014-10-31)".
